CVE-2023-3247

Name of the Vulnerable Software and Affected Versions PHP versions 8.0.* through 8.0.28 PHP versions 8.1.* through 8.1.19 PHP versions 8.2.* through 8.2.6

Description The issue is related to the use of a random value generator with a narrower range of values than it should have when using SOAP HTTP Digest Authentication. In case of random generator failure, it could lead to a disclosure of 31 bits of uninitialized memory from the client to the server, and it also made easier to a malicious server to guess the client's nonce.

Recommendations For PHP versions 8.0.* through 8.0.28, update to version 8.0.29 or later. For PHP versions 8.1.* through 8.1.19, update to version 8.1.20 or later. For PHP versions 8.2.* through 8.2.6, update to version 8.2.7 or later. As a temporary workaround, consider disabling the SOAP HTTP Digest Authentication until a patch is available.
